OLIVER ELLSWORTH, OF NEWTON, MASSACHUSETTS.-

IMPROVEMENT IN CURTAIN ROLLERS AND BRACKETS.

Specification forming part of Letters Patent N 0. 170,072, datedNovember 16, 1875; application filed May 11, 1875.

To all whom it may concern:

Beit known that I, OLIVER ELLSWORTH, of Newton, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements-in Curtain-Fixtures; and I do hereby declare thatthe following is a full, clear, and exact description thereof, whichwill enable others skilled in the art to which it pertains to make. anduse the same, reference being bad to the accompanying drawings, and tothe letters of reference marked thereon, which form a part of thisspecification.

Figure l is a section through the center of the roller andthe pinion, asseen at war in Figs. 2 and 3. Fig. 2 is an interior view of the bracket,showing the gear-wheel, pinion, and dog; also the method of joining thefoot to the bracket. Fig. 2 is a face view of the foot. Fig. 3 is asection of the bracket on y 3/ .of Fig. 2. Figs. 4. and 5 aremodifications of the dog. Fig. 6 is a perspective View, showing thechange to make an inside fixture.

The nature of this invention relates to the I manner of fastening thespring-bracket to the foot'piece, so that the bracket may bereadilydetached, and, without the foot, be secured to the inside jamb of awindow; also, to the dog or ratchet, which is counterbalanced, all ofwhich will be more fully hereinafter described.

In the drawing, A is the upper frame orcasin g of a window. B is theroller, on which is fastened the shade. G is the shell or metallic case,in which are the spring-gear, dog,

&c., having a waist, G, with eyes 0 c. D is the gear-plate, having teethon the inside of the rim or flange. D is the hub cast with theplate,having a raised washer, D, and a shoulder, D, at the inner end,and a similar shoulder at the opposite end at D, Fig. 1. E is the pinionE, the stem of the pinion, flattened at the end to suit the socket inthe end i of the roller-plate having a shoulder at c. F

is a dog or ratchet, which is pivoted on the box or case 0, its innerend being fastened by a mortise-notch to a pin on the surface of the hubD. The outerend of the spring G is looped, and the screw 9 passesthrough it and secures it to the casing at g. H is the footpiece havingin it grooves h h and notches h. In these grooves and notches are fittedthe projecting ridges and ribs 0 0 on the waist plate or waist 0,through which wood-screws can be passed to fasten the bracket to theinside casing or jamb, and a corresponding bracket with a socket toreceive the other end pivot is screwed to opposite jamb.

When this is done the bracket does not hold the same position as whenused for an outside fixture, but is turned one-quarter around.

The advantages of this fixture over those now in use is in the facilityof converting it into an inside from an outside fixture simply byremoving the foot-piece. Also, in the dog being counterweighted, so thatit always acts upon the teeth of the pinion, and arrests with certaintythe shade within a small space where it may be desired, say, withinthree-quarters of an inch movement of the shade.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. The foot H, with the grooves 70. and h, and the spring-bracket withribs and guides c, all constructed substantially as and for the purposedescribed. 1

2. The'oounterbalanced dog F suspended to the spindle of a maingear-wheel, in combination with the pinion-wheel E.

In testimony that I claim the foregoing as my own invention Iaffix mysignature in presence of two witnesses.

OLIVER ELLSWORTH.
